[Characteristics of capsular bacteria, isolated from children with acute intestinal diseases].

A study was made of 256 young children suffering from gastroenterocolitis, dyspepsia, food poisoning for the presence of conditionally pathogenic representatives of the Enterobacteriaceae family. Klebsiellae were isolated in 39.8% of the patients and in 22.3% of 67 healthy children. A study was made of morphological, cultural-biochemical properties and the antigenic structure in 308 strains of the Klebsiella denus. Capsules were detected by microscopic examination. Biochemical properties were determined after Kaufman, and some of the cultures proved to differ from the typical biochemical pattern described by this author. K-antigen was found in 185 klebsiella strains; of this number 99 strains belonged to Kl. pneumoniae and 86--to Kl. aerogenes. Fimbria were revealed in some of the Kl. pneumoniae and Kl. aerogenes strains. Bacteriocines were detected in 103 of 206 strains (by Abbot and Shennon's method).
